Title: Picture forming device
Inventor: MURANO SHUNJI
IPC: B41J2/45
Filed: 1989-09-21
Abstract: PURPOSE:To simplify the constitution and to improve the print speed by giving a switching signal to 1st and 2nd switching elements for each block of a print data generated from a data generating source so as to switch the storage order to the memory elements alternately for each block. CONSTITUTION:A print data from a data generating source is stored in plural memory elements F1-F64 in forward and reverse directions by one block each with the operation of 1st switching elements 77-82 and 2nd switching elements 83-88. The storage output of the memory elements is given to one terminal of a print element to decide a predetermined level and a level of common signal lines VK1-VK40 of a relevant block is decided to the other level. Thus, each print element is energized based on a print data sequentially along with the arrangement direction. Thus, the constitution is simplified in comparison with a conventional device, the rearrangement of the print data is not required and the print speed is improved.

Title: Fitting device for exposure head of image forming device
Inventor: NIWA MINORU
IPC: G03G15/04
Filed: 1990-09-17
Abstract: PURPOSE:To enable secure and accurate positioning with simple configuration by fitting and exposure head to a bracket in a position adjustable state so that the pressing force to a leaf spring member varies when the position is adjusted. CONSTITUTION:The gap between the tip of the exposure head 3 and a photosensitive body 1 is accurately adjusted with the elastic force of a leaf spring 25 and the clamping force of a nut 41, and the position can securely be held. Further, the exposure head 3 is held at a constant position while the parallelism and angle of rotation to the shaft of the photosensitive drum 1 are accurately held because of the balance between the anticlockwise force of the leaf spring 25 on a center G of gravity and the clockwise force from an abutting piece 24. Heat generated by the exposure head is conducted to the whole bracket through a leaf spring member and radiated efficiently.

Title: Ignition timing control device for engine
Inventor: KATO MASAHIKO
IPC: F02P5/15
Filed: 1993-09-09
Abstract: PURPOSE:To improve deceleration performance while preventing engine stall at the time of rapid deceleration by delaying more delay angle operation of an ignition timing, the more opening degree of a throttle valve and rotational speed of an engine are large at the time of rapid deceleration of the throttle valve. CONSTITUTION:In a fuel injection and ignition timing control unit 33, an ignition means 25 is controlled on the basis of the detecting signal of a throttle opening degree detecting means 35. Namely, when the opening degree of a throttle valve is small, an ignition timing is set to a delay angle side. When the opening degree is large, the ignition timing is set to an advance angle side. At this case, rapid deceleration operation is judged by a judging means on the basis of the detecting signal of a throttle valve opening degree detecting means 35. On the other hand, an operation range data just before rapid deceleration operation is memorized by a memory means while detecting a prescribed operation range by a detecting means. At the time of rapid deceleration of the throttle valve, the more the opening degree of the throttle valve in just before thereof or rotational speed of an engine is large, the more delay angle operation of the ignition timing is delayed.

Title: Reliabilty design method
Inventor: KOYAMA KAZUKUNI
IPC: H01L21/82
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a reliability design method for reducing the price of a system by decreasing the number of components to be added in order to satisfy the reliability required for the system and reducing the control function block for managing a duplex function block. SOLUTION: Excess failure rate is calculated (Step 503) for each block in an electronic system by subtracting a reliability allocated to a function block from the failure rate accumulated for the components in function block (total sum). When a component having higher failure rate than the excess failure rate is present in a concerned function block, components having lowest failure rate are duplicated. Consequently, the unavailability for duplicated component is brought close to '0' (Step 504 - Step 518) and the reliability allocated to the concerned function block is satisfied.
